Los Angeles is like that too. I worked a grant panel last spring and my husband and I drove around a bit. MacArthur Park, west of downtown, is a homeless CAMP. It looked the size of a Boy Scout Jamboree - acres and acres of tents, homeless folks. And Wilshire Blvd. I would not work down there for love nor money. Even the offramps right off the freeway. What is wrong with the Mayor? The liberals??
I'm a native Angeleno. I can remember when McArthur Park was a real park. It was pleasant, well kept, and a great place for an afternoon picnic. Not a bum, a druggie, or a gangster in sight.
I haven't driven past there since the early 90s, but even then, it was still void of homeless people.
I don't know how a city or state reverses such conditions. Looking at examples like Detroit, it will predictably get worse and worse, until the bottom falls out.
Then comes Armageddon.
